It is a JDM b18c, which is equivilent to a b18c1 but with 10.6:1 compression and an optional LSD tranny. The valve cover is just for looks. As far as color goes, I am not 100%, but it is going to be some shade of blue. Daytona blue which is what Nissan uses on the the 350z is what I am steering towards, though. Lastly, I have an A'pexi N1 cat-back, but I just through on a stock axle back on the car to have one less thing to mask while painting.

very nice engine I was goin to let evryone know it was a b18c gsr and that you could tell by the intake mani btu E beat me to it so anyhow nice motor and well ahhh nice strip job on the car anyway hope to see it when its all done mang!
